Hi Allan, Jus came across your post about the little wenlock and sounds like the exact same issue that i am facing. the fire burns out very quickly and appears to be excessive amount of air even with the bottom wheel fully closed. noticed from some other comments that this is probably by design for being a SE burner but wanted to know did your workaround of using fire rope help resolve the issue ? do you mean the 2 slits on either side of the vent lever ? how did you fix the rope to the burner ? any help would be gratefully appreciated as its quite frustrating at the moment as we are getting through a lot of logs every evening. thanks
